### Avoiding permanent beta

From Kubernetes 1.20 onwards, SIG Architecture will implement a new policy to transition all REST APIs out of beta within nine months. The idea behind the new policy is to avoid features staying in beta for a long time. Once a new API enters beta, it will have nine months to either:

 - reach GA, and deprecate the beta, or

possible for large applications to migrate incrementally. The Maven group ID
is now `com.squareup.okhttp3`. For an explanation of this strategy, see Jake
Wharton's post, [Java Interoperability Policy for Major Version
Updates][major_versions].

This release obsoletes OkHttp 2.x, and all code that uses OkHttp's
`com.squareup.okhttp` package should upgrade to the `okhttp3` package. Libraries

non-experimental `Policy`, there is no loss scale associated with the `Policy`, and `Model.compile` wraps the optimizer with a `LossScaleOptimizer` if and only if the policy is a `"mixed_float16"` policy. If you previously passed a `LossScale` to the experimental `Policy`, consider just removing it, as the default loss scaling behavior is usually what you want. If you really want to customize the loss scaling behavior, you can wrap your optimizer with a `LossScaleOptimizer` before passing it to `Model.compile`....

- Promoted Job Pod Replacement Policy to general availability. The `JobPodReplacementPolicy` feature gate was locked to `true` and will be removed in a future Kubernetes release. ([#132173](https://github.com/kubernetes/kubernetes/pull/132173), [@dejanzele](https://github.com/dejanzele))...

- Disallow setting a resize restart policy of `RestartContainer` on non-sidecar initContainers, as the resize of such containers has never been supported. ([#137458](https://github.com/kubernetes/kubernetes/pull/137458), [@natasha41575](https://github.com/natasha41575)) [SIG Apps, Node and...
